Beginning in the 1950's, a system of lakes, ponds and spillways was built by the Soil Conservation Service to catch and hold floodwaters in the Plum Creek Watershed, with the water then released at an engineered rate, minimizing damage from heavy rains.

Plum Creek Conservation District monitors, maintains and improves this system to ensure that it works properly, maintaining 28 flood control structures and managing underground water resources in parts of both Hays and Caldwell Counties.

The Edwards Aquifer Authority (EAA) is a regulatory agency established by the 73rd Legislature in May 1993 with the passage of the Edwards Aquifer Authority Act to preserve and protect this unique groundwater resource. However, legal challenges prevented the EAA from operating until June 28, 1996. Today, a 17-member board of directors representing Atascosa, Bexar, Caldwell, Comal, Guadalupe, Hays, Medina, and Uvalde counties continues its mission. Teams of geologists, hydro-geologists, environmental scientists, environmental technicians, educators, and administrative staff collaborate daily to manage, enhance, and protect the Edwards Aquifer for the approximately 2 million South Texans who rely on the aquifer as their primary source of water.

The missiong of the HTGCD is to conserve, preserve, recharge and prevent waste of groundwater within western Hays County. In support of the District’s mission, we provide educational materials and information about our water resources.
